AN AIRCRAFT FATIGUE MONITORING SYSTEM.
GRUMMAN AIRCRAFT ENGINEERING CORP BETHPAGE N Y
A report on the development of a fatigue damage indicating system, based on the use of metal monitors bonded to the airplane structure, is presented. The development of the system includes a series of laboratory tests to determine suitable monitor designs, and to evaluate various adhesive systems. Monitor installations on the full scale fatigue tests of both the Grumman A6-A Intruder and E2-A Hawkeye airplanes are also evaluated. Results of tests indicate that further development work is necessary, and various recommendations are made. Author
